Miscellaneous WLAN-based localization me¬thods focus on preferably precise location estimation and tracking. However, the infrastructure of a WLAN system can also be utilized for relative spatial assessment within discrete zones, not using a reference coordinate system. This paper proposes a WLAN-based localization prototype that is capable of unambiguously distinguishing detached interac¬tion zones, allowing applications to imitate near field com¬munication (NFC). Operation is accomplished by customary mobile devices not equipped with NFC technology but a WLAN interface. A prototypical payment scenario at cash¬desks in a store proves the concept, where customers are required to securely show their electronic store card, i.e., bring their mobile device into a near, non-interfering zone to their cashier. The paper provides measured figures revealing clearly distinguishable interaction zones in WLAN environ-ments
